Motor

This pump has a hollow shaft. It fits straight onto the shaft of a hollow-shaft motor or engine, so there is no flange or coupling between them. You need a hollow-shaft motor of at least 1.6 kW.

Flange

None needed: the pump fits straight onto a hollow-shaft motor.

Coupling

None needed: the pump fits straight onto a hollow-shaft motor.
